A Laboratory for Star Formation

The stars become more sporadic throughout the rest of the image, glittering against a black backdrop of space and nebulous indigo clouds that glow in the picture’s lower half. Credit: NASA, ESA, R.

Location: In the Carina spiral arm of our Milky Way Galaxy

Distance from Earth: About 20,000 light-years

Object type: Nebula and open star cluster

Discovered by: Sir John Herschel in 1834

Imaged here by the Hubble Space Telescope, NGC 3603 is a collection of thousands of large, hot stars, including some of the most massive stars known to us. Scientists categorize it as an “open cluster” because of its spread-out shape and low density of stars. Surrounding the bright star cluster are plumes of interstellar gas and dust, which comprise the nebula part of this cosmic object. New stars are formed from the gaseous material within these clouds! NGC 3603 holds stars at a variety of life stages, making it a laboratory for scientists to study star evolution and formation. Astronomers estimate that star formation in and around the cluster has been occurring for 10 to 20 million years.
